Apple lines overexpressing MdTyDc maintain a stronger photosynthetic system after 15 days under control and alkaline conditions. (A,B) Net photosynthesis (Pn) under (A) control and (B) alkaline conditions, (C,D) intercellular CO2 concentration (Ci) under (C) control and (D) alkaline conditions, (E,F) stomatal conductance (Gs) under (E) control and (F) alkaline conditions, and (G,H) transpiration rate (Tr) under (G) control and (H) alkaline conditions. The data are presented as means ± SD (n = 5). Significant differences between WT and MdTyDc overexpression lines are indicated by different lowercase letters based on Tukey’s multi-range test (P < 0.05). WT, wild type. OE-2, MdTyDc overexpression line 2. OE-3, MdTyDc overexpression line 3. OE-5, MdTyDc overexpression line 5.
